About Merge Audio
Join several songs, voice memos or recordings into a single audio file, played back to back in the order you add them. You can insert up to 5 seconds of silence between tracks and choose MP3, WAV, M4A, OGG or FLAC for the result.
When it helps
- Combining several voice memos or recording segments into one file
- Building a continuous mix or playlist file for an event or workout
- Joining audiobook chapters or lecture parts that were split into pieces
- Stitching an intro, main recording and outro together for a podcast
Tips
- Files can be different formats, sample rates and channel counts; each is converted to 48 kHz stereo before joining so they line up cleanly.
- A 1 to 2 second gap sounds natural between separate songs; use 0 for segments of one continuous recording.
- If the tracks are at very different volumes, run each through Normalize Audio first so the merged file is even.
